Abstract

The invention discloses a high-performance ultra-fine grained hard alloy new material splitting cutter, belonging to the technical field of hard alloy cutters. The high-performance ultra-fine grained hard alloy new material splitting cutter is manufactured by adopting a powder metallurgy process, and consists of the following raw material components in percentage by mass: 0.40-0.50% of CT, 85.0-85.5% of WC, 12.0-12.5% of Co, 0.4-0.6% of Vc, 0.7-0.9% of Cr3C2, 0.6-0.8% of TaC and 0.03-0.07% of octadecanoic acid. By adopting an ingenious new formula of an ultra-fine grained material, the problems of pores, non-uniform distribution of a Co phase and the like caused by poor wet milling dispersion are effectively solved from the ingredients, thus a high-quality mixture is prepared, and the slitting and shearing cutter with high performance and high precision is produced; and the cutter has high hardness, high strength, strong abrasion resistance and good toughness, and the quality and comprehensive use performance of the cutter are in the domestic leading position.

Description

technical field [0001] The invention relates to the technical field of cemented carbide cutting tools, more specifically, relates to a high-performance ultra-fine-grained cemented carbide new material slitting and cutting knife, which is suitable for CNC cutting of machine tools in the lithium battery industry, metal film, and printing and packaging industries. knives. Background technique [0002] Since the new century, with the rapid development of my country's manufacturing industry, a large number of domestic CNC equipment and assembly lines have entered various fields, and a sharp contradiction soon surfaced-advanced equipment cannot be equipped with advanced domestic mechanical tools. foreign knife. Luo Baihui, secretary-general of the International Mold and Metal Plastic Industry Suppliers Association, said that high-quality carbide cutting tools have become the main tools required by processing enterprises in my country, and are widely used in heavy industries such a...
